Inventor: WADA KATSUO
IPC: F02C7/232
Filed: 1983-07-08
Abstract: PURPOSE:To keep stable combustion upon low load without spoiling the low NOx characteristics of the combustor by a method wherein the position of the fuel nozzle can be moved on the axial line of the combustor to utilize an air pressure at the entrance of the combustor, which is proportional to the load of the combustor. CONSTITUTION:Gas fuel enters from a flange 4, passes through the center of a piston rod and a swirler 6, then, is injected from the nozzle under being sent by the air in the swirler. Combustion is generated in a primary combustion area immediately after the fuel nozzle while dilution holes 8 are provided to introduce much amount of air and effect combustion. When the load of the combustor is reduced, the air pressure at the entrance of the combustor becomes small in accordance with the load, therefore, a piston 3 moves upward by the force of a spring 10 and the tip end of the fuel nozzle moves to the upper end of a combustor liner 7 together with the swirler 6. In this case, the dilution holes do not affect to the primary combustion area, therefore, the optimum air-fuel ratio in accordance with a no-load condition may be set. The movement of the fuel nozzle is continuous from no load to a rated load, therefore, the stability of the flame of combustion may be excellent at any load.

Abstract: PURPOSE:To reduce cost and to bring a liquid developer into gradual contact with a photosensitive surface by providing a mechanism which rises and lowers the level of the liquid developper with respect to a developing head. CONSTITUTION:When a developing soln. tank 21 is risen, the liquid developer 20 in the tank 21 flows through a communicating pipe 24 and contacts a photosensitive body 31a in entering the inside of a developing chamber 23.

Title: Impeller for centrifugal compressor
Inventor: ORIGASA HIDEAKI
IPC: F04D17/08
Filed: 1994-06-06
Abstract: PURPOSE:To reduce disc friction loss in an impeller by providing a guide vane for suppressing percolation by generating flow retrorse to percolation, on the outside of an impeller main plate. CONSTITUTION:When gas leakage flow 7 from a following stage impeller inlet passage 6 passes between an impeller main plate 2 and a static passage 4, friction to the impeller main plate 2 is generated so as to generate disc friction loss. Since the gas leakage flow 7 is leakage flow from the following stage impeller inlet passage 6, the velocity component of leakage flow is only a radial velocity component. Since gas flows in a place where an impeller 1 is rotated, large friction is generated on the main plate side of the impeller 1. In order to suppress this leakage flow, a guide vane 9 is provided on the outside of the impeller main plate 2. The guide vane 9 is fitted in such a way as to have a negative angle to the rotating direction tangent of the impeller 1, and gas flow 11 inward from the outside is generated by the wedge effect. Leakage flow from the following stage impeller inlet side passage 6 is thereby suppressed.

Abstract: PURPOSE:To minimize extremely the wear even in an image holding body having an OPC photosensitive layer and to remove completely the residual toner by setting an angle to form an image holding body surface and a cleaning blade to 60 deg. or above. CONSTITUTION:To obtain a high cleaning effect without increasing the rotating load of the image holding body as much as possible, it is desirable to abut the cleaning blade so that an Ft component of an abutting load Fa can be large and an Fn component can be small, and consequently, it is desirable to provide the cleaning blade so that theta can be large, alpha can be small and the value theta-alpha can be large, and when Fn is excessively lower, the equal abutting to the image holding body surface of the cleaning blade comes to be hard, the removal of the toner comes to be incomplete, and therefore, it is necessary to consider that an Fn value should obtain the suitable value. Namely, in the cleaning device to abut the compound layer type cleaning blade of the supporting body layer and the elastic body layer to the image holding body having an OPC layer, theta>=60 deg. is obtained on the premise as mentioned above.
